Additional Information
High Efficiency: Reduces energy costs by up to $92.00 per lamp* when replacing a 120W halogen with a 39W CMH® (requires new fixture). Provides 4 times more lumens per watt than comparable incandescent or halogen lamps.
Twist and Lock Base: Ensures secure alignment and easy installation with a robust base to reduce pin degradation.
Color Uniformity: Constant Color CMH-GU6.5 lamps deliver a consistent "white look" for color-critical applications like retail display.
Excellent Color Rendering: 81 CRI nominal, capable of up to 94 CRI for vibrant, accurate colors.
Long Life: 12,000-hour rated life extends relamp cycles and reduces maintenance costs.
Compact Design: T4 tubular design with quartz envelope maximizes fixture optics for efficient light output.
Fast Restart: 5-minute hot restart time (vs 10-15 min for larger CMH lamps).
Replacement Parts: 20W M156 ballast and GU6.5 sockets available.
Warning
UV Radiation Hazard: This lamp can cause serious skin burns and eye inflammation from shortwave ultraviolet radiation if the outer envelope is broken or punctured, and the arc tube continues to operate. Do not use where people will remain for more than a few minutes unless adequate shielding or other safety precautions are used. Certain types of lamps that automatically extinguish when the outer envelope is broken are commercially available.
Enclosed Fixture Required: This lamp has an unprotected arc tube and MUST be used in enclosed fixtures only.
Ballast Required: This is NOT a line-voltage lamp. Requires ANSI C156/M156 LFSW electronic ballast.
Operating Temperature: Max base temp 250°C, max bulb temp 400°C.
